Abstract
Although the electrical discharge process is a material removal process, it is attempted to be used for surface operations as well, so considering the new method, it is important to analyze the mechanism of the electrical discharge surface alloying process. Nickel base alloys are widely used due to their high resistance to corrosive environments, especially at high temperatures, especially in environments where stainless steels and duplexes lose their performance. This paper first discusses the mechanism of surface alloying by electric discharge method and then, as an experimental work, examines the surface alloying of aluminum with nickel-copper alloy (Monel 400) to improve its surface properties. Therefore, the parameters of pulse on time and pulse current are considered as input parameters and the depth of hardened layer as output variable. The results of this study show that using Monel 400 electrode with negative polarity as an alloying electrode is a successful method to improve the surface properties of aluminum by eliminating harmful layers resulting from electrical discharge machining.
